p. 3 Symantec Corporation Symantec Intelligence Report :: JANUARY 2014 Executive Summary Welcome to the January edition of the Symantec Intelligence report. Symantec Intelligence aims to provide the latest analysis of cyber security threats, trends, and insights concerning malware, spam, and other potentially harmful business risks. A number of large data breaches were reported during the month of January. The largest new data breach included the exposure of 105.8 million identities in South Korea. (It’s worth noting that many individuals in the country had more than one account exposed in this breach.) Another large data breach, previously reported as including 40 million identities, has since had its numbers adjusted upwards and is now estimated at 110 million identities exposed. These two breaches contribute significantly in bringing the total number of identities exposed to over 500 million for the last twelve months. Targeted attacks are up to their highest level since August of last year, after what appears to be average-to-low attack numbers over the last four months. Manufacturing is the most targeted industry, making up 21.3 percent of attacks. The non-traditional services category, which includes hospitality, recreation, and repair, is a close second at 20.6 percent. The number of vulnerabilities reported is also up in January after lower numbers reported in November and December of last year. However, at 555 vulnerabilities, this number is still well below October, which reported a high of 663 for the month. In other news, spam and phishing rates are down slightly in January, while email virus rates are at their lowest levels since October of last year. We hope that you enjoy this month’s report and feel free to contact us with any comments or feedback. Ben Nahorney, Cyber Security Threat Analyst firstname.lastname@example.org

p. 10 Symantec Corporation Symantec Intelligence Report :: JANUARY 2014 SOCIAL MEDIA
p. 11 Symantec Corporation Symantec Intelligence Report :: JANUARY 2014 Social Media At a Glance Top 5 Social Media Attacks Source: Symantec • 82 percent of all social media attacks in January where fake offerings. • Likejacking is the secondmost common type of social media attack at 8 percent. Top 5 Social Media Attacks 82% Fake Offering 8% Likejacking 5% Manual Sharing 2% Fake Apps 2% Comment Jacking Methodology Fake Offering. These scams invite social network users to join a fake event or group with incentives such as free gift cards. Joining often requires the user to share credentials with the attacker or send a text to a premium rate number. Fake Plug-in Scams. Users are tricked into downloading fake browser extensions on their machines. Rogue browser extensions can pose like legitimate extensions but when installed can steal sensitive information from the infected machine. Likejacking. Using fake “Like” buttons, attackers trick users into clicking website buttons that install malware and may post updates on a user’s newsfeed, spreading the attack. Fake Apps. Applications provided by attackers that appear to be legitimate apps; however, they contain a malicious payload. The attackers often take legitimate apps, bundle malware with them, and then re-release it as a free version of the app. Manual Sharing Scams. These rely on victims to actually do the hard work of sharing the scam by presenting them with intriguing videos, fake offers or messages that they share with their friends.

The Norton CCI is a statistical model that measures the levels of threats, including malicious software, fraud, identity theft, spam, phishing, and social engineering daily. The data breach section of the Norton CCI is derived from data breaches that have been reported by legitimate media sources and have exposed personal information. In some cases a data breach is not publicly reported during the same month the incident occurred, or an adjustment is made in the number of identities reportedly exposed. In these cases, the data in the Norton CCI is updated. This causes fluctuations in the numbers reported for previous months when a new report is released.
